Answer:
1/2 or 50%
Step-by-step explanation:
There are 4 total cards
The number of odd or 5 is 3 or 5 so a total of 2 choices
P(5 or odd) = { 5 or odd}/ total
= 2/4
=1/2
C and D is true and others are false
Answer:
y= -2x+3
Step-by-step explanation:
first find the slope=-2
determine one point like(0,3)
then use formula
y-3=-2x
y= -2x+3
It would be: 0.25 = 25/100 = 1/4
so, your answer is 1/4
Each roast beef cost $4 and each vegetarian sandwich cost $2.5
Let x represent the cost of each roast beef and let y represent the cost of each vegetarian sandwich.
Bhargav buys five roast beef and three vegetarian sandwiches and the order costs $27.50. This can be represented by the equation:
5x + 3y = 27.50 (1)
Bhargav buys 2 roast beef and 6 vegetarian sandwiches and the order costs $23.00. This can be represented by the equation:
2x + 6y = 23.00 (2)
To find x and y, we have to solve equation 1 and 2 simultaneously. Multiply equation 1 by 2 and subtract equation 2 from the result:
8x = 32
x = 4
Put x = 4 in equation 2
2(4) + 6y = 23.00
6y = 15
y = 2.5
Therefore each roast beef cost $4 and each vegetarian sandwich cost $2.5
